Roller coating is a coating process used to apply liquid paints, inks, or other coating materials evenly onto flat or rolled substrates. It's an automated, cost-efficient process requiring minimal labor to create uniform thin layers on the material's surface.

Roll-to-roll coating is an efficient method for processing large surfaces, offering advantages like consistent coating quality, high production efficiency, and suitability for various types of coatings. It's ideal for large area substrates like rolls and sheets.

Most flat objects, such as doors, glass windows, and wooden floors, are suitable for roller coating. The process can be applied to materials like glass, stainless steel, wood, plastics, and cork.

With our specially designed roller coating equipment, it's possible to apply UV primers on cabinets and specially shaped doors in certain cases.

Yes, coating lines typically comprise roller machines for base coats and spray machines for surface treatments, offering a comprehensive solution.

Using roller coating technology, you can achieve various levels of smoothness on flat surfaces, whether transparent or colored, matte, semi-gloss, or glossy.

Each roller coater downstream requires a gel/drying machine, which can be a UV or hot air oven, depending on the type of coating applied. Additionally, machines for sanding primers, cleaning panels with brush machines, and conveyors are also needed.

For high-quality coating on straight edges with radii and unique shapes, vacuum technology is required. Roller technology is more suitable for smaller-radius straight edges.

All coated materials require drying. The type, duration, and method of drying depend on the paint's properties and quantity.

There are two main categories of coating drying: physical drying and chemical drying. The former relies on hot air, airflow speed, and time, while the latter requires a light source, usually lamps. Some paints require both methods for drying.

Excimer drying is a drying process for UV coating products that achieves a truly excellent deep matte finish on surfaces.

Inert atmosphere drying is achieved by significantly reducing the amount of oxygen in the oven and replacing it with inert gas, like nitrogen. This type of drying can reduce the photoinitiator amount needed for UV coatings to start the crosslinking process by 40-70%, significantly saving costs.

Besides substantially reducing the need for photoinitiators and thereby lowering paint costs, inert atmosphere drying has other benefits. The paint used is less harmful to the environment. Yellowing effects caused by photoinitiators are less likely to occur. Fewer UV lamps are needed to activate crosslinking, reducing energy costs.

  • The coating must be matched with the substrate material to ensure proper adhesion.
  • The size of the coated workpiece must be able to pass through the spraying system.

  • Firstly, the spray coating process ensures that all sides of a workpiece are covered.
  • Secondly, the shape of the product doesn't matter, and since it's a non-contact-type coating, different tolerances between products are automatically compensated.

It depends on the type of spraying machine, the type of conveyor (paper or continuous belt), and the type of filter (paper or water). The basic steps include setting up the spraying equipment, adjusting the spray guns, preparing the coating material, doing a test spray, and then proceeding with the actual spraying operation. It's relatively simple but still requires some professional skill training.

Due to the use of dual coating rollers, the liquid can be circulated and more evenly covered on the panel, resulting in no paint waste, more environmental friendliness, and higher processing efficiency.

Dual roller coating machines can use UV, PU, PE, water-based paints, and adhesives.

Dual roller coating machines can process wood, glass panels, metal sheets, PVC boards, marble, and other materials.

This is a continuous surface coating system that uses multiple roller coatings to achieve thicker coatings. It can coat wood panels, glass panels, metal sheets, and other panel materials.

A UV coating, also known as ultraviolet coating, is a transparent, glossy liquid applied to printed materials. This coating is a popular printing technique used to protect items that are frequently handled during delivery.

PU coating has excellent resistance to chemicals, acids, alkalis, salts, and petroleum products, and is less prone to cracking and peeling. UV coating is known for its high hardness, good wear resistance, transparency, scratch resistance, and rub resistance.

Aqueous coating is generally used in places with higher environmental requirements, and it requires a longer drying time. UV coating uses ultraviolet light to cure the coating, which is very easy to cure and harden, and has good wear resistance and chemical resistance. It's commonly used in the printing industry, packaging industry, woodworking industry, etc.

A UV roller coating system typically consists of roller coaters located downstream of UV ovens and upstream sanding machines. These coating lines can be customized according to specific requirements and are very suitable for manufacturers who need to repeatedly process the same large batches of products.

  • The settings of the coating machine are very simple and easy to operate.
  • Less downtime and higher efficiency, resulting in a higher return on investment for users.
  • The spraying system is very easy to maintain.
  • The spraying process of the spraying system is very easy to control to ensure paint consumption and quality assurance.

Roller coating can be used for surface finishing of different materials in many industries. In particular, it is the ideal solution for processing flat panels. Some of the areas using this technology include:

  • Woodworking industry
  • Ceramic manufacturing industry
  • Metal sheet processing industry
  • Cardboard processing industry
  • Furniture manufacturing
  • Plastic sheet and film manufacturing, etc.

Using surface finishing technologies has promoted the development of new furniture products. Our more flexible, reliable, and efficient coating production lines can produce higher quality furniture and furniture panels, improving the processing efficiency of furniture manufacturing enterprises, as well as higher quality surface treatments, making furniture products more popular with buyers.

  • Using reliable finishing technologies can ensure the durability and wear resistance of the floor, and also have higher floor processing efficiency!
  • We focus on customer requirements and achieve the desired floor quality through individually planned coating production lines and unique coating production processes.

  • Glass coating is becoming more and more important in the glass manufacturing industry and can achieve the diversity of glass applications.
  • We use more efficient glass panel finishing systems to shorten glass coating times for glass manufacturing enterprises, as well as to achieve more types of glass processing.

The most important cost factor in the coating process is paint consumption. We improve paint recovery systems, increase paint recovery rates, and intelligent paint systems can help you monitor paint consumption in real time.
